Corsair CX600M PSU review -
Certification and Efficiency

Certification

So, Corsair offers a PSU with a 80+ Bronze certification, tested by the 80PLUS organization (the people that certify and test efficiency). We already explained a little what that literally means. But what does such a certification entail?

Well, we have standard, bronze, silver, gold, and platinum certifications. A PSU that is certified 80 PLUS Gold or 80 PLUS Platinum is more efficient than a normal unit. Below you'll find a table that shows what efficiency levels a PSU has to achieve at a given load to make the grade for a specific certification level.

The Corsair CXM 600W power supplies are certified by the 80PLUS organization to deliver a 85% energy efficiency at 50% load and still 82% efficiency when your PC idles. The product complies with the ErP (Energy Related Product) directive to ensure less than 1W of power is used in passive standby and off modes. We'll test that manually later on in the article.

Above, you can see a diagram of how the PSU behaves efficiency wise.

Corsair CX Series ATX PSU

CX Series Modular power supply units are an excellent choice for basic system builds and desktop PC computer upgrades, offering high reliability, low noise, easy installation. The flexible modular cabling system lets you use only the cables you need, and 80 PLUS Bronze certified efficiency means less excess heat, lower noise, and lower power bills. The large-diameter, thermally controlled fan makes the CX Series Modular quieter at idle, and the large diameter reduces noise even when you’re pushing your system hard. And, the matte black finish, black-sleeved cables and black connectors help give your system a restrained, high-tech look.

Modular CablingThe modular cabling system lets you use only the cables you need. You get to save space and reduce clutter for a cleaner-looking build and improved airflow.

Reliable and CompatibleCX Series Modular is built and tested to strict standards for trouble-free installation and smooth operation..

Modular Cabling SystemSince the peripheral power cables aren’t hard-wired to the power supply, you can connect only the cables you need for your exact configuration of PCI-E cards and storage devices. The rest of the cables stay in the box, and not in your PC’s case where they can add to the clutter and interfere with airflow.

Large-Diameter, Thermally Controlled FanOnce you’ve installed a PSU, you shouldn’t have to think about it. Employing a thermally controlled fan makes the CX Series Modular quiet at idle, and the large diameter reduces noise even when you’re pushing your system hard.

Black Goes with EverythingYou’re building a PC, not a battleship, and appearance counts. The matte black finish and all-black sleeved cables and connectors help give your system a high-tech, restrained look.
